LOCKING CLOSURE I03 BEOEPTACLES.

Application mu January 3, 1025. Serial I0. 300..

To all whom it may comern: Be it known thatI, FAY K. Rows, a citizen of the United States, residing at Burns,

in the county of Marion and State of Kansas, have invented certain new and useful Improvements in a Locking Closure for Be. ceptacles, of which the following 1s a specification.

This invention relates to improvements in closures for metallic receptacles and has for its primary object to provide means for locking the closure in the filling opening of the container after the latter'has been filled whereby any unauthorized person will be prevented from removing the fillingopening closure and discharging the contents, or

7 otherwise polluting the liquid.

One of the important objects of the 'present invention is to provide a device of the above mentioned character, which is adapted to be associated with a bung or bung hole in a metallic receptacle, the locking device being readily and easily actuated, the same being further simple in construction, inex pensive, strong and durable and furthermore adapted for the purposes for which it is designated.

A further object of the invention is to provide a device of the above mentioned character, wherein the same provides a unitary structure thus preventing the accidental displacement, of the locking means associated with the closure.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawlng formin a part of this specification and in which like numerals designate like parts throughout the same Figure 1 is a top plan view of the bung shofiving the locking means associated therewit Figure 2 is a bottom plan view, and

Figure 3 is a sectional yiew.

In the drawing, wherein forthe purpose of illustration is shown. the preferred embodiment of my invention, the numeral 1 designates a portion of a suitable metallic container, the same being provided with a hung hole whereby the tank may be filled with the liquid to be stored therein. A flange 2 is formed around the bun hole and provides a means for su porting 1n the latter the bushing 3. The ushing is internally threaded and provides a means for receiving the threaded bung 4 which provides a closure for the filling opening.

A substantially hexagonal head 5 is formed on the upper end of the bung 4 and a gasket 6 1s interposed between the top of the bushing 3 and the bottom of the head 5 as is clearly illustrated in Figure 3. Y

F or the purpose of locking the bung 4 against removal from the bushing 3 after the container has been filled, a disc 7 is adapted for rotation on the bottom of the bung 4 and is further, adapted for cooperat1on with the bottom of the bushing 3 in the manner to be presently described. The disc 7 is of a diameter slightly less than the diameter of, the threaded portion of the bung so that when the disc is in an unlocked position, the same will be disposed against the bottom of the bung 4 in the lustrated at 10 so that the outer end 11 The lever 9 is twisted intermediate its ends as il-- thereof will be disposed at substantially right angles to the inner end of the lever, the inner end being arranged in a substantially horizontal plane, while the outer end is disposed in a'vertical plane. The outer end 11 of the lever 9 isprovided with an opening 12, the same being adapted for registry with a similar openlng 13 formed in the upstanding portion of an angular lug 14 which is secured on the top of the head 5 as at 15.

An abutment or stop 16 is formed on the top of the head 5. When the locking disc 7 is in the position as shown in the dotted lines in Figure 2, the lever 9 will be in the position shown in dotted lines in Figure 1 so that the samewill bein engagement with the abutment 16. This construction permits the bung to be removed from or inserted within the threaded bushing 3. After the container has been filled and the bung threaded in the bung hole bushing, the pin 8 is rotated by moving the lever 9 toward the angular lug 14. This will cause the simultaneous rotation of the disc 7 whereby the same will be brought into engagement with a portion of the bottom of the bushing 3 as illustrated more clearly in Figures 2 and'3. A. padlock or the like shown at 17 of any conventional construction is then inserted through the registering openings 12 and 13 formed" in the forward portion 11 of the lever 9, and the upstanding portion of the angular lug 14 respectively.

When the parts are arranged as shown in Figure 3, the bung may not be removed from the threaded bushing in the bung hole unless the proper key is placed in the padlock for unlocking the same in order that the lever 9 may be moved to the osition as shown in the dotted lines in igure 1 so that the locking disc 7 will be returned to its position within the confines of the bung so that the bung may be easily removed from the threaded bushing,

The provision of a locking closure of the above mentioned character, will thus prevent the loss of the fiuid contents of the container as access thereto cannot be h when the filling opening is looked as well as the discharge spigot. Furthermore, the provision of alocking closure of the above mentioned character, will prevent any possibilit of the liquid contents being polluted, suc as is frequently done and which renders the li uid unfit for its proper use. a

y constructing a bung witha locking means of the character above described, a unitary structure is provided which will at all times enable the locking means to be readily used.

While I have shown the preferred em-- bodiment of my invention, it is to be understood that various changes in the size,

shape and arrangement of parts may be resorted to without de arting from the spirit of the invention an the scope of the appended claims.

Having thus described the invention, what I claim is 4 1. A locking closure for a container having an opening therein, a bushing supported in said openin a hung threaded in said bushing, a bee of said bung, a vertical pin arran ed eccentricall within said bung, a loc ing disc secure eccentrically on the lower end of said in and being of a diameter less than the diameter of the hung, a lever associated with the upper end of said pin for rotating the same whereby the disc is moved into locking engagement with the bottom of the bushing, and means associated with the lever for holding the disc in its locked position.

2. A locking closure for a container having an opening therein, a bushing supported in said opening, a bung threaded in said bushing, a head formed on the upper end of said bung, a vertical pin arranged eccentrically within said bung, a locking disc secured eccentrically on the lower end. of said pin and being of a diameter less than the diameter of the hung, a lever associated with the upper end of said pin for rotating the same whereby the disc is moved into locking engagement with the bottom of the bushin means associated with the lever for holdmg the disc in its locked position, said means comprising a lug on the top of said head, and a padlock extending through the free end of the lever and said lug.

In testimony whereof I afiix my signature;

FAY K. ROWE.
